Carboxy to ketone dimeric and catemeric hydrogen bonding in a keto acid phosphorane: X-ray structure of 6-ethoxycarbonyl-5-oxo-6-(triphenylphosphoranylidene)hexanoic acid
Abstract
Single-crystal X-ray crystallography revealed carboxy to ketone catemeric and dimeric hydrogen bonding in separate crystals of the keto acid phosphorane 1.
